Model the asset before you build it.
I’m Rehan Khan, a digital twin lead based in Cologne. I help owners, architects, engineers, and contractors turn buildings and infrastructure into living digital systems — modeled before groundbreaking, integrated through construction, and monitored for decades of operation.
Fraunhofer-certifiedDigital Twins Business ConsultantOne model, read by everyone who touches the building.
Owners & Developers
See true lifecycle cost and risk before capital is committed, and carry one model from pro forma to disposition.
General Contractors
Clash-checked sequencing and a single source of truth that keeps field teams and subs working from the same model.
Architecture & Engineering
BIM that stays synchronized across disciplines, with a readiness check before design intent becomes field reality.
Facility Operations
A live operational twin that flags failures before they happen, instead of a static model that goes stale at handover.
Three disciplines, one continuous model.
Engagements typically combine services across advisory, delivery, and operations — scoped to where your project sits today.

From readiness to a model that keeps working.
Assess
A DT Readiness Assessment maps your data, systems, and goals against what a digital twin actually needs to deliver value.
Model
I build the twin: BIM-integrated geometry, systems data, and the logic that keeps it synchronized with the real asset.
Integrate
The twin connects to IoT sensors, building systems, and operational feeds — live, not a one-time snapshot at handover.
Operate
Lifecycle simulation and predictive maintenance keep the twin, and the building, ahead of problems instead of reacting to them.
Illustrative engagements.
Composite examples representative of the engagements I take on, not named clients.
Transit Hub Modernization
A digital twin of a multi-platform transit hub, built to coordinate four construction phases without closing live platforms.
Outcome: fewer sequencing conflicts, clearer phase handoffs (illustrative)
Riverside Health Campus
A readiness assessment and phased IoT rollout gave facilities staff a live view of critical systems across three buildings.
Outcome: faster fault detection, consolidated monitoring (illustrative)
